TSP (libtsp) - FLdirName

FLdirName

Routine

int FLdirName (const char Fname[], char Bname[])

Purpose

Return all but the last component of a file path

Description

This routine takes a file path specification and returns all but the right-most component of the file name. Components are separated by "/" characters. If no "/" character appears in the name, an empty string is returned. For Windows, the directory separator character is "\".

Examples:

   "abc/def"      => "abc"
   "abc/def/"     => "abc/def"
   "abc/bcd/def"  => "abc/bcd"
   "/abc/def"     => "/abc"
   "/abc/bcd/def" => "/abc/bcd"
   "./def"        => "."
   "def"          => ""

Special cases:

   "/def"         => "/"
   "/"            => "/"

Parameters

<- int FLdirName: Number of characters in the output string
-> const char Fname[]: Input character string with the path name
<- char Bname[]: Output string with the all but the last path name component. This string at most FILENAME_MAX characters long including the terminating null character.
